Lack of interestThread Prefixes + Viewing Permissions

Member

Is it at all possible to make thread prefixes behave like forums in terms of permissions? As in, not only can certain groups use certain prefixes (as is available in XF now), but only those groups can even see the threads with those prefixes? In other words, the prefixes are determining permissions for that thread within the forum. Such as if certain groups can view the thread with that prefix, reply to it, etc.
